A boat hull shield is disclosed including a hull perimeter bracket adapted to attach to a boat hull, the bracket extending along a port and a starboard chine of the boat hull. The hull shield further includes a convex panel, with a low-friction hard surface, for covering a bottom surface of the boat hull, having an outer edge retained by the bracket, extending from the port chine to the starboard chine of the boat hull, the convex panel forming a hollow space between the convex panel and the boat hull. A trim component is included in the hull shield which is attached to the aft end of the boat for adjusting an angle of a surface of the convex panel. The hull shield also includes a suspension component for absorbing impact force on the low-friction hard surface of the convex panel.
